Abstract

There is provided a method for designing a device (500), comprising: determining a strain limit of a material (502), the material comprising a coating, the strain limit being the strain value which the material can accommodate before the coating cracks; and designing at least one portion of the device (504) based upon the determined strain limit, the device comprising the material.
